The framework u sed to secure the sound insulation ceiling assembly II a is sound-proofed by similar v l' to the ceiling.` blocks or bats |29 of sound-insulating material 55 positioned between the inner walls of the assembly and a sup-porting framework composed of an upper frame of angle irons I3I and a lower frame of angle irons |33, secured in spaced relationship by a plurality of straps |35, the upper ends |31 of which are fastened to rib 22 of the ceiling assembly by bolts |39 passing through apertures 23a. and I4I.

In the construction shown in Fig. 10 the outer wall I is not doubled back but is strengthened at its upper edge by an angle iron 39 which extends completely around the booth except in that portion above the doorway. The ceiling II is then secured to the angle iron 39, while a modified backing plate 3|a is secured to the wallI Y'above the doorway. At one point, preferably. `in the front of the booth, where the one-piece outer wall I is joined together, anges 40 are bent inwardly from the outer wall I and welded `at 4 to form a projecting rib which cooperates.` with a f' to the level of the bar 45. Secured to the insideV of outer wall I medially of Yeach of the two side wall portions thereofY aretwo columns 49 of door lspreader bar cross section, extending likewisel from the floor to the level of the bar v45. An opening in the web of Z bar 45 affords communication between the interior of columns 49 and the space above the lower level of ceiling II. A pair of channel members 5| positioned on each side of the doorway and extending from the iloor to the top of the doorway support the front wall portion of outer wall I which is `welded thereto. Sheet metal panels 53, extending about the side and back walls'of the booth, form the inner booth wall. These panels extend from Y`the level of Z bar 45 to aboutsix inches from the floor and completely close the space between the adjacent columns 41. Spring flanges 55 on the side edges of each panelY enable the panels to be snapped into place between the columns 41 and held tightly in position -while remaining readily removable. The upper Yedges `of the panels 53 are clamped between the bar 45 and an angle iron `51 by means of -machine screws 59.

In Fig. 5, slightly modified panels 53a are provided with inturned flanges 56 on their upper edges, and are thus held against possible downward slipping.

The space between the panels 53 and the outer wall is filled with sound insulating material 54 preferably formed in compressible bats or slabs of slightly greater original thickness than the space between the walls.

The oor assembly 6| is formed by Ablanking out a piece of sheet metal into the' shape shown in Fig. `6, radial corrugations -53 being formed at the samer time. Sections 65 -are then bent up at right angles to section 64, `sections 51 are dished downwardly so as to bring the corners -68 almost but not'quite yto the level of corrugations 63, and section 69 is bent back upon section 64 and tapped yholes 10 made in the doubled portion.

The floor and wall yassemblies are joined by welding the lower portion of wall I to the upright portion 65 `of the licor assembly. A sheet metalV `the space 2.9.

spacer 1| is then welded in place on the inside of the lower portion of wall I, and a composition flooring 13 laid over the iioor 64 and up against Y the spacer 1| for a height of about six inches to form a baseboard 14. A metal protecting strip 15 extends across the floor at the doorway opening and is secured by screws 11 set in the tapped holes 10. The upper edge of the baseboard 14 is secured to the spaced 1| by a U-shaped molding clip 19 which is snapped over and engages the baseboard 'I4 and -a flange 8| extending upwardly from the spacer 1|. This molding clip .19., also serves to retain the lower edge of panels '53 forming the inner wall in place. If desired,

thefnioiding clips 19 may be formed as an integralpart .of the panels 53.

' A seat83 is'mounted on a spindle 85 which in 'turn is` secured in a base or socket member 81.

Bolts 89 secure the base 81 through the baseboard '14 to the spacer 1|.

The hollow cylindrical standard I1 is secured to the floor 64 by any suitable means (not shown) andis secured at its upper end in the aperture I5 in ceiling I. The stan-dard I1 is secured a xed sleeve 93 carrying a bracket 9| and slidable onthe standard I1 are two sleeves 95, 91 carrying brackets 99, E0 I. Securable to the brackets 9|, 99, v10| in two positions so as to be secured at two heights from the floor is backboard |03 and shelf |05 secured thereto, which serve to carry the telephone instrumentalities. A-pertures l|01 in the standard I1 serve to permit the necessary wiring for the telephone instruments to be carried intoV the interior of the standard. The specific construction of the telephone stand above described and its connection to the standard I1 is described in more detail in my copending application Serial No. 122,363, led January .26, 1937, and is speci cally claimed therein. Y

The door |09 of the Vtelephone booth will preferably be formed of sheet metal, and desir-Y ably will be of the two leaf type specifically described and claimed in my copending application Serial No. 120,324, led January 13, 1937. The door, however, may be of any conventional type. It is supported by hinges III secured to one of the channel columns 5|. The free edge of the door is guided from'openrto closed .position by means of a roller Vor ball bearing assembly ||3 secured in a bracket II5 mounted on the upper edge of the door |09 and traveling in track ||1 of channel cross-section supported by lbrackets IIB secured to the spacer plate 3| and the outer wall AWiring for the supply of electric current to lights, fan, etc. (not shown), positioned in the space 29 above the ceiling will be brought to the top of :the booth, carried around the booth to the point desired in the channel I9 of channel member 2|, and passed through apertures 23 to These apertures 23 also serve as air inlets to space 20for Ventilation purposes.

The Vtelephone wiring will be brought into theV space y29 in the same manner and theny passed through aperture I5 down the interior of column |71 and so through holes |01 to the telephone instruments on shelf |05. The vertical channel I2! in the side walls of the booth formed vby channelmember 49 and outer wall y| may also; bey

used for wiring purposes. Access to this channel may be had through the bottom by piercing the iioor 51 andthe horizontal portion ofspacer 1I,

through the top by piercingi'lange I9 of the ceiling, angle iron -51 and -Z Abar 45, 0r throughV the Y side by piercing only thefo'uter wal-l 1|.

I do not claim specifically herein the floor assembly hereinbefore shown and described, since this is specifically claimed in my copending application Serial No. 120,323, filed January 13, 1937.
